How do I post a new issue that includes a custom field value?

Hello

So I'm using Power Automate to help manage tickets from a different platform and posting new tickets on our JIRA project board.

I can POST a new issue with a summary and description using the HTTP nodes. For our project we have an additional custom field that I'd like to be able to assign a value when we create a issue; this custom field shows up in the Details panel. I'm not using the built in connector that comes with Power Automate as the node doesn't seem to have a field that let's me create an issue with a custom field value. Instead, I'm using Power Automate HTTP node to do a POST request

The following JSON is what I'm passing to the HTTP Body which let's me create a ticket

{
  "fields": {
  "project":
  {
    "key": "TJP"
  },
  "summary": "New JIRA Ticket.",
  "description": {
    "type": "doc",
    "version": 1,
    "content": [
       {
         "type": "paragraph",
          "content": [
           {
             "type": "text",
             "text": "Test ticket"
           }
           ]
       }
    ]
  },
  "issuetype":
  {
     "name": "Task"
  }
 }
}

What do I need to add to the above to populate the custom field? If it helps, I think I've narrowed the custom field's attribute to customfield_10054 (is there a simpler way to reference this? Will this change between different projects?)

Thank you

Nevermind, it seems like I was referencing the wrong customfield reference as well as using the wrong attribute within the customfield. My json body now looks like this:

{
  "fields": {
  "project":
  {
    "key": "TJP"
  },
  "summary": "New task with customfield set",
  "description": {
    "type": "doc",
    "version": 1,
    "content": [
    {
      "type": "paragraph",
      "content": [
      {
        "type": "text",
        "text": "Setting the task's Technology to PowerBI"
      }
      ]
    }
    ]
  },
  "issuetype":
  {
    "name": "Task"
  },
  "customfield_10055": {
    "value":"PowerBI"
  } 
 }
}

Still, is it possible to retain the customfield attribute name between different projects? I notice that for one project, that field is customfield_10055 (in this case) but it becomes something different in another.
